    摘要: A liquid crystal display according to the present invention can prevent interference fringe on a display panel due to a switching noise of a DC/DC converter, therefore a high-quality image can be displayed. Either of input signals for a timing control circuit is also supplied to a PLL circuit and the DC/DC converter is controlled by an output signal of the PLL circuit, thereby enables to synchronize a switching frequency of the DC/DC converter and control signal.

    摘要: A thermal head for a thermal printer and/or a thermal ink transfer printer having a substrate, a heater layer and a conductive lead layer on the substrate in which a protection layer covering the heater layer has been improved. According to the present invention said protection layer is made of polyimide resin which includes some hard particle of filler of S.sub.i C with a weight ratio to the polyimide solid in the range between 1.1 and 3.2. Since the present protection layer is provided with low curing temperature, the substrate of the present thermal head may be polyimide resin which is not heat-proof. Because of filler in the protection layer, that protection layer is wear-proof, although polyimide layer itself is not wear-proof.
